Many people / engineers around me talk about trendy stuff like Cybersecurity or AI and show off what great encryption and neuronal networks they 'have built' ( I would rather say 'using').

I kinda get the feeling of 'Everbody talks about it - no one really knows what's goin' on inside (especially those guys who hate math and even algorithms).'

Am I just stupid or does somebody else here feel the same way? I mean people have been doing serious research about this stuff for years. And currently many kids are coming up with it as if it is easy stuff like the bubble sort.
